3 1 SCOPE 1.1 Identification The development design and delivery of a train number input module. This document presents the requirements of the Train definition unit required by Spoornet. 1.2 System overview It is critical to operations at Spoornet that all locomotive data communications are indexed with a Spoornet allocated train identification number. This train number is a unique reference to a train movement as well as its locomotives and wagons consist. This number is issued to a train driver at the beginning of a train trip for purposes of identification for communications and authorizations. Spoornet requires a unit to allow the train driver to input this train number and transmit it via the Spoornet Locomotive Communications Unit to a central database within the Spoornet WAN at the beginning and end of a train trip. The train number will thus be available to other systems in the locomotive during a train trip and cleared at the end of the trip. The status of a train trip will also be available on a central database in real time. The diagram in Figure 1 shows the context diagram of the Integration of the train definition unit with Spoornet s locomotive communications infrastructure to the Spoornet WAN. The blocks with the colored background in Figure 1 represent the parts of the system required by Spoornet, while other components shown represent systems outside of the scope of the specification, and only shown for information purposes.

Train Definition Unit Ruggedized Day/Night Alphanumeric Display Window PSU (POE) VDC Ruggedized Alphanumeric Input Keypad 10/100 Mbps Ethernet Port Controller with Power Over Ethernet (POE) Figure 2: Train definition unit components Controller The communication infrastructure that Spoornet employs entails a TCP/IP Local Area Network (LAN) on each locomotive. This network is connected to the Spoornet Wide Area Network (WAN) using various data communications options. The communication units employed in Spoornet locomotives connect the locomotive network to the Spoornet network with GPRS, WiFi and UHF Radio. The communications mediums connect directly to the Spoornet WAN or through multiple land-based access points at various control centers in the country under the control of the Train Control Officers (TCOs). Information such as date-time stamp, GPS coordinates and locomotive identification number is broadcast on all the Ethernet ports of the communication units or made available on request. The information is broadcast in the form of TCP/IP and UDP/IP packets. Two servers on the Spoornet WAN are available to execute the supplier messaging software, and are either a Linux, or Microsoft based server. The Train definition units shall employ the Power Over Ethernet interface for its power requirements. 2 DOCUMENT OVERVIEW 2.1 APPLICABLE DOCUMENTS The following specifications, standards and drawings of the exact issue form a part of this specification to the extent shown herein.
